O Rose thou art sick

the invisible worm.
that flies in the night
in the howling storm:

has found out they bed
of crimson joy:
and his dark secret love
does thy life destroy.

Is it correct to identify "in the howling strom:" and "of crimson joy:" a caesura that commands the reader to pause, and enjambment would be the line "and his dark secret love" that runs into the next line "does thy life destroy." which becomes a line that is considered end-stopped?

I think you're right about enjambment, but I'm not convinced about the caesuras you have identified. Please read over the definitions again and rethink this.
